Figure 12.4 Communication between Flash and the HTML page using fscommand
The variable ‘str’ is the input box that you can see in Figure 11.4 displaying the string ‘Flash calling’.
When ‘fscommand’ is called for Internet Explorer, if the HTML page contains a VBScript Sub
‘xxxx_FSCommand(cmd, args)’ where ‘xxxx’ is the ID used for the Flash object, then this subroutine
is called. When fscommand is called for Netscape, if the HTML page contains a JavaScript
function ‘xxxx_DoFSCommand(cmd, args)’ where ‘xxxx’ is the name used for a Flash embed, then
this function is called. A VBScript can call a JavaScript function on the same page using the form
‘call functionname(parameter1, …)’. In the example the VBScript function ‘flash_FSCommand’
calls the JavaScript function ‘flash_DoFSCommand’ using the ‘call’ method.
In this instance Flash affects the actual page by setting the document object with the ID ‘flashStr’,
which is the SPAN of the one item table, to the value passed in the variable ‘args’.
